What is a CSS Class
Hi there. This video is all about a class selector. Okay. It's going to allow us to do this. Okay. Where we style the yellow box differently from the pink box will do the same thing with this P tag will make one P tag different from the other one. That is the job of a CSS class selector. Let's jump in now and learn how to make it work. Okay, so here's our CSS. This thing here is called a type selector. So it's selecting all the div types. But the problem is it's quite generic goes every type that happens to be a div do this stuff to it and that's why we have a class selector. So what we want to do is let's been all of this. Okay, put my returns back in Tabin. So instead of deciding all dibs on every page of the same thing, let's create what's called a class selector. So all it means is I get to be unique. I get to say I'm going to create a class to know it's a class and not like that type selector. We just did you put a full stop in the front of it in your CSS. Okay that says I'm a cla...
ss. What kind of class? I'm gonna give it a name. You can call it anything you like we're gonna call box one. Okay then like the rest of the CSS we've been doing it's the same. So curly braces return and then we style it so that little full stop at the beginning means I'm a class. Okay. What are we going to do to that class? We're gonna say it's a background color, background color of yellow, semi colon. We're going to have a width and height with 600 PX by the height of 400 peaks. Cool. So we've got box one. Now it there's no way of kind of connecting these two yet. Okay. So it says hey box one be yellow. But down here it's like, well I don't know what you're applying it to. So what you do is you leave the div and what you do is afterwards put a space and open the word class. Okay. You can see V. S. Co really wants to help out. Okay if you're typing it out, make sure you put in the equals and the quotation marks. So we have a div class and what we want to do is apply box one. Okay. So now that is attached the differences are just to make sure that when you're styling it up here in your CSS you have to use the full stop to say I'm a class down here. You have to be a bit more long winded. Okay, So you say class equals and you don't put that dot in there. Okay. That won't work. So class long version. Short version now. Hopefully if we save. Okay. And we go to stir in a browser, we reset and the first box now knows it's yellow and it knows that it's 600 by 400. This box. Okay. Down here has no idea what it needs to be. So let's tell it it's the same before let's make a second class. You ready? So dot box too. Okay. Put in curly braces and we'll tell it we will steal all this because I'm lazy. Okay. But we want this one to not be yellow. We want it to be that pink color. Oh that's not a color to be pink. Cool. Save It. It's the wrong size and weight while size in height. 400 x 250. So I just made up these sizes. You can type anything you like. 400 By 250. Save it. And now it's not gonna work. Why is it not gonna work? Let's check refresh just to confirm it's not working because we haven't applied it to it so we've styled it now. We need to apply it down here after the word. Div typing class and you can see there the way I work. I'm going to work a little bit more shorthand as we work through. You can start writing all the syntax if you like. But you'll notice that I space C. That's all I've done and I'm going to return on my keyboard or the enter key and it fills in all that lovely syntax. I type in box to save now. Hopefully refresh. Hey there we got our first box and a second box and it vaguely resembles this. Cool. Huh? So we learned what a type selector was. You don't need to remember that name but a class selector for CSS is something we're going to do a zillion of in this class and it's a way of individually targeting this. So instead of box one, this might be hitter and this might be navigation and this might be main content and we get to style them, color them inside them. Let's go a little bit further and add a little bit of styling to it and look at a class selector but in a different kind of context. So back in Vegas code here, I've got two p tags and they look exactly the same in the browser. Okay, let's say I want to make this one a different color and a different size. So instead of tiling the p tag like we did earlier, remember we made all the H one's okay. But the problem is is that every H one on every page. Whereas this one, I just want this little unique guy in the first box to do something. So up here underneath box one or box to I'm going to put in another class remember has a full stop And I'm going to call this one my highlight highlight highlight highlight text. Okay you have to put a space in then you have to put in your curly braces. Okay, your curly braces next to your Peaky and then we're going to say I'd like you to be a color in the background color for the background color and just regular old color if you want to style text and let's say I want to make this, what are the crazy colors we've got in here? Mm Gonna make this dim gray. Okay, they spell it both ways. Look at that. Cool. Alright, let's put in our semi colon. Okay, and let's make the font size, so font size, just something really big so we can kind of just easily see it. Okay, so I've saved it now we need to apply it and it's the same thing. I can say you there's a P tag but also a class of dot, not diet. It was a test of hormone test highlight text. Let's save it. Let's check it. Refresh. Hey, it is bigger and it's the grain. So you style the type selectors to do kind of big general broad strokes. Okay then you do little specific things using classes and you apply them to individual little bits and pieces. You can use it twice. There's no reason why we can't say you're my friend also have a class of highlight highlight text and it will apply to both of them. Hopefully it didn't. Okay, and you're like you see why I have no idea why because now I pretend like I put that in there on purpose but that is always my problem. You might not be as grammatically challenged as I am, but I find it very hard to type this stuff in. So like when I'm not doing tutorials and trying to impress you with my typing speed. Okay? I copy and paste everything copy and paste. It is painfully slow, but it gets around my problem of typing the wrong word in and then trying to fix it. Not working out what it was, it's just because of typos, let's delete this and I'll show you some other tricks for kind of just making sure yeah you can keep up or fix any errors. So the easiest way is to compare against the father I'm making. So say it looks like you've done the same thing, But it's not actually working for some reason is in your exercise files that you've downloaded. Okay, you will find in that folder there's something called the completed files and in here I've zipped up. That was the fifth video that I made. This is the sixth video. So if you're watching this video it's probably what are you up to? I think video 10. You will find I haven't finished this video yet. So you'll find a folder in here cord. Oh 10. No it would be oh 10. It'll be 10. Okay. And you can open that up. Um And open up. So let's just do one. Okay, I double clicked it, open it up and there's the stuff we're working on and you can just open this obvious code. So go to file, open and compare yours versus mine. Okay. And I'll do that throughout the course. That's one of the ways you can check your code. The other things to note or I guess to check. And these are the things that I find my students run into when I'm teaching live classes is people forget the full stop. Okay to identify a class or they start adding the class dot down here which you're not meant to. One that always catches people out is they'll accidentally delete one of these. Okay the curly braces and because that one opens and then doesn't close, okay it kind of freaks out of it doesn't you can see it's changed the highlighting color a little bit but it's just kind of missing. So often you can go through click on this. Okay find your click on that first bracket and you can see it's highlighted the closing one. If I click on this one it won't click on it because it doesn't know where the ending is. Okay so it won't highlight its buddy. Let's put his buddy back in there he is. Now if you click on them they kind of just connect to each other. Here we go. The other things are people forgetting to put Collins in and semi colons in just basic syntax problems. Basic spelling mistakes. Like I do all the time. We'll do a bit more error checking later on. We'll install some plug ins for V. S. Chrome. sorry. V. S. Code to help us with that syntax errors. But for the moment, those are the basic ones. And that'll be it for this video. Let's get on to the next one.
